Online RSVP is a Godsend

I know that people have varied opinions on having guests RSVP on the internet vs. through the mail, but let me just say that the time-saving tool that is the online RSVP has been amazingly awesome. When guests respond, I get an email sent to me and it keeps me constantly updated on the head count for our caterer. Guests also enter their email addresses so if FI and I have any questions (or need to tell them that extra "and guest" they added is NOT coming to our wedding) we can correspond easily. People really have no excuse not to RSVP now since most of them use the internet daily anyway, and the best news is no worrying about response cards getting lost in the mail! Hooray for technology!
